As a matter of practicality, for Enterprise Architecture to be successful, there are many things that have to work out before, in parallel with, and after Enterprise Architecture efforts result in an Enterprise Architecture. There are governance things going on, there are development things going on, there are operations things going on. Each of these areas can benefit from some good old Enterprise Architecture thinking and, as well, Enterprise Architecture success needs these areas to be successful! Again, Enterprise Architecture is not THE answer, it is part of something bigger.
